Application filed March 1, 1912. Serial No. 680,938.

To all whom it may concern:

Be it known that ll, EDWIN D. BELKNAP, a citizen of the United States of America, residing at New ork cit'y, county and State of New York, have invented certain new and useful Improvements in Stencil-Cards, of which the following is a specification.

My invention relates to stencil cards such as are usedin quantities in addressing machines for addressing envelops, post cards, wrappers and the like. These cards consist of a thin sheet of prepared paper in which a name and address are stenciled, and a surrounding frame of cardboard, paste board or other stifi'er material. It is frequently desirable to make said frame with a wide margin on which various reference or classification marks may be placed, as shown generally in my U. S. Patent No. 898,425, of September 15, 1908,"but when such wide stiff frames are used certain difliculties are encountered in forming and handling'the stencil cards which it is the object of my present inventionto overcome.

In-the accompanying drawing, Figure '1 shows a face view of a stencil blank. Fig. 2 is an end view. Fig. 3 is a face View of a card before the stencil has been formed. Fig. 4 is a cross section on line 44 of Fig. 3. Fig. 5 is a face view of a completed card. Fig. 6 is a cross section'on line 6-6 of Fig. 5. Fig. 7 is a face view of another card and Fig. 8 is a cross section on line 8- -8 of Fig. 7, parts being broken away.

Throughout the. drawings like reference "characters indicate like parts.

1 is a blank of prepared paper which is usually too limp to be conveniently handled in a typewriter. In such case a thin flexible frame 2 is fastened to it by pasting or otherwise before it is run through the typewriter. A stiff frame can not be used in this stage of the process because it will not bend and the curvature of the typewriter platen roller. This frame is not stiff enough, however, to'be conveniently handled in the addressing machine, and a second frame 3 (see .Fig. 8) is then pasted to the other side of the card to complete it for t such use.

VVhen'a paper is used stiff enough to be handled in the typewriting machine without a reinforcing frame, a single stiffening frame 4 (see Fig. 6) is all that need be added to prepare the card for use in the addressing machine. After the card is written the reference or classificationmarks may be made on the wide portion of the frame, as shown in Figs. 5 and 7. When these heavily reinforced frames are used .the 'frames are apt to warp, and then, when they have reinforcing frames on both sides and are stacked in a magazine, the projecting inner edges of one card frame are apt to catch on those of the next card as each card is forced out of the magazine by the feeding device of the printing machine, or when a card is placed in or withdrawn from' a magazine or file case, for correction, change or addition of a new name, etc. To avoid this difliculty, I

make two of the opposite inner edges of the frames curved, as shown in Figs. 5 and 7 concavely'to the body or middle portion of the card so that they bow outwardly "one from the other, or are otherwise shaped so that no two opposite portions of the said two inner edges of the frame will be parallel to each other, but always present outlines inclined one to the other. The frames will then slide one over the other without catching even when one is bent so as to project below the plane of the face of the next card,

when slid over or under it, itbeing understood of course that the cards are slid over one another in use on a line parallel to the uncurved inner edges of-the frame.

Having, therefore, described my invention, I claim:

1. A reinforced stencil card comprising in combination a sheet of stenoilized paper and reinforcing frames on each side, two of the opposite inner edges of each frame being so shaped that their outlines at opposite points I are always inclined. one to the other.

2. In a reinforced stencil card the combination of a stencilized sheet, and reinforcoutwardly one from the other.

ing frames attached thereto on each face, of the; opposite, inner edges of the frame two opposite inner edges of each frame bebeing formed in continuous curves bowing 10 ing formed in continuous curves, bowing outwardly one from the other.

3. A reinforced stencil card comprising-in EDWIN BELKNAP' combination athin sheet of stencilized paper, Witnesses: and a reinforcing frame of thicker, stiffer H. PARKERHU'RST,
